The multiscale modeling methods are one of the most investigated subjects in literature in recent years. Their wide range of applications covers many fields of science, including innovative materials and production engineering. This paper presents algorithms of multiscale modeling implemented on heterogeneous architectures, which are applied to simulate metal forming production processes. The influence of the different computing devices on obtained results as well as efficiency of proposed algorithms are discussed within this work. The computations are verified using a process of ribbed rod heat treatment.

Modeling of blood flow with respect to rheological parameters of the blood is the objective of this paper. Casson type equation was selected as a blood model and the blood flow was analyzed based on Backward Facing Step benchmark. The simulations were performed using ADINA‐CFD finite element code. Three output parameters were selected, which characterize the accuracy of flow simulation. Sensitivity analysis of the results with Morris Design method was performed to identify rheological parameters and the model output, which control the blood flow to significant extent. The paper is the part of the work on identification of parameters controlling process of clotting.

The algorithmic and computational aspects of 3D finite element numerical integration on GPUs are investigated in the paper. The special stress is put on selecting the proper parallelization strategies depending upon the properties of FEM problems solved and approximations used. The close interplay between the available computational resources of GPUs and the possible implementation strategies and obtained results is observed.

We present a strategy to develop a mesh manipulation module of a flexible and robust adaptive finite element application that will perform accurate modelling of flows, handling complicated computational domains. We describe guidelines for developing such a module focusing on three aspects: parallelism on domain and computational node level, improving speed through better cache hit-ratio and assuring flexibility thanks to modern object oriented programming techniques. In subsequent development the module is intended to bu used in multi-physics and multi-scale simulations of fluid-structure interactions.
